Detailed explanation-1: -Hooke detailed his observations of this tiny and previously unseen world in his book, Micrographia. To him, the cork looked as if it was made of tiny pores, which he came to call “cells” because they reminded him of the cells in a monastery.
Detailed explanation-2: -When he looked at a thin slice of cork under his microscope, he was surprised to see what looked like a honeycomb. Hooke made the drawing in Figure below to show what he saw. As you can see, the cork was made up of many tiny units, which Hooke called cells.
Detailed explanation-3: -Hooke cut a thin slice of cork with a penknife, put it under his microscope, focused sunlight on it with a thick lens, and looked through the eyepiece. What Hooke saw looked like a piece of honeycomb. The cork was full of small empty compartments separated by thin walls.
Detailed explanation-4: -Robert Hooke was the first person who observed the cells. He examined small pieces of cork obtained from the bark of trees through his simple microscope. He observed many small box-like structures and named them as cells which means little room.
